Step 1 of 3 11.004E Refer to the Example 11. 1in the text book. R, + A V₁ V₀ V. + R₂ R₁ The open-loop gain AM is: Upper 3-dB frequency of before negative feedback is: WH = 100 Hz = kΩ and = 9 kΩ Step 2 of 3 Calculate the value of feedback factor = 1+9 = 0.1 Now, calculate the Low-frequency gain A, of a closed loop amplifier = 10000 = 1001 =9.99 V/V Hence, the required answer is: 9.99 V/V Step 3 of 3 Calculate the Upper 3-dB frequency of a closed-loop amplifier = = 100.1 kHz Therefore, the required answer is 100.1 kHz.
